Hmm, only just started on my 92 8v, but from cold it's really juddery like it's going to cut out, driving and on idle. This is only when the engine is cold, once it warms up it drives fine as. If you start driving straight away it'll judder and have a lack of power, keep your foot planted and it'll pick up sooner or later. Seems like a possible fuelling issue, any ideas? Both pumps are running fine, might change the blue temp sensor but any other ideas?
